Abstract
Particular embodiments described herein provide for an electronic device that can be configured to include a sandwich plate construction heatsink. The sandwich plate construction heatsink can include a cold plate, one or more heat pipes over the cold plate, and a top plate over the one or more heat pipes. The cold plate can include a channel to accommodate the one or more heat pipes and/or the top plate can include a channel to accommodate the one or more heat pipes. The cold plate can be over a heat source in the electronic device.
Claims14
A sandwich plate construction heatsink over a heat source on a printed circuit board, the sandwich plate construction heatsink comprising:
- a cold plate coupled to a retention mechanism that includes leaf spring elements coupled to the printed circuit board;
- one or more heat pipes over the cold plate;
- and
- a top plate over the one or more heat pipes, wherein the top plate is coupled to the retention mechanism to secure the top plate over the one or more heat pipes, wherein the leaf spring elements of the retention mechanism create an applied load on the cold plate.
An electronic device comprising:
- a printed circuit board;
- a heat source located on the printed circuit board;
- and
- a sandwich plate heatsink over the heat source, wherein the sandwich plate heatsink includes:
- a cold plate over the heat source, wherein the cold plate is coupled to a retention mechanism that includes leaf spring elements coupled to the printed circuit board;
- one or more heat pipes over the cold plate;
- and
- a top plate over the one or more heat pipes, wherein the top plate is coupled to the retention mechanism to secure the top plate over the one or more heat pipes, wherein the leaf spring elements of the retention mechanism create an applied load on the cold plate in a direction towards the printed circuit board.
An electronic device comprising:
- a printed circuit board;
- a heat source located on the printed circuit board;
- a package stiffener around the heat source;
- and
- a sandwich plate construction heatsink over the heat source, wherein the sandwich plate construction heatsink includes:
- a cold plate over the heat source and coupled to a retention mechanism that includes leaf spring elements coupled to the printed circuit board;
- a plurality of heat pipes over the cold plate;
- and
- a top plate over the plurality of heat pipes, wherein the top plate is coupled to the retention mechanism to secure the top plate over the plurality of heat pipes, wherein the leaf spring elements of the retention mechanism create an applied load on the cold plate in a direction towards the printed circuit board.
